There is an ongoing debate in the marine world arguing that cephalopods use their camouflage to communicate with each other. A cephalopods camouflage is made up of a bunch of tiny chromatophores in their skin. Several scientists think that the communication is plausible, while others stick to the no-fun result that there is not a bit of proof.
In order to understand if cephalopods use their chromatophores to communicate, it might be a good idea to know what a cephalopod is. A cephalopod is in the class of mollusks that scientists classify octopuses, squid, and cuttlefish. They can change color faster than a chameleon or a salamander or many kinds of fish. They can also change texture and body shape, and, and if those camouflage techniques don't work, they can still "disappear" in a cloud of ink, which they use as a smoke-screen. They're jet powered, they suck in a lot of water and spit it out really hard to make them move faster. Cephalopods have inspired legends and stories throughout history and are thought to be the most intelligent of invertebrates. They have eyes and other senses that are awesome and are way better than people and most animals.
A better way to understand if they communicate using their chromatophores, it might be best to know exactly what the chromatophores are and what they can do. Camouflage is the most important defense action in cephalopods. The cephalopod chromatophore system has captivated people since squid and octopus and cuttlefish were discovered. Chromatophores are specific cells which can contain or produce pigment, or reflect light in a precise way to create a certain desired color. The system is the only known example of skin reflectance under direct neural control, as opposed to the...

... the arm raise to mean something more complicated or maybe even different from whatever stripe means by itself,” says Jennifer Mather. Mather is a psychologist who studies cephalopod behavior and teaches at the University of Lethbridge in Lethbridge, Alberta. , Her thinking this is intriguing, but it remains unexplored and still unproven. Besides camouflage, I think that cephalopods use the chromataphores for communication. There are documentaries about the Humboldt Squid where they were more aggressive toward humans in one isolated area than they were everywhere else. In the documentary it is seen that they flash bright red to white not only to show panic, but they show lower down toward more squids that when one squid was showing panic, the rest must have seen it as a sign danger was ahead. I’m not a scientist, but I’m almost positive that is communicating.
Because of its size and abundance, T. californicus is commonly regarded as the insect of the sea. This creature is generally very small, from 1-3 mm in size as adults. They are cylindrically shaped, and have a segmented body (head, thorax, abdomen) though no noticeable division between body regions (Powlik 1966). Each segment of the body has a pair of legs. They use their 'legs' to propel themselves through the water in short rapid jerks. They have 2 pairs of long feathered antennae, a chitin us exoskeleton and a single eye in the middle of their head, this simple eye can only differentiate between light and dark.
In the lab the isopods were observed in a way to where behavior and structures could be properly recorded. The isopods were revealed to two dissimilar scenarios, normal temperature water vs. warm temperature water, to calculate which environment was most preferred. In each distinct scenario ten isopods were placed ten a choice chamber, one side being normal temperature (26.7celsius) and the other being warm temperature (43.3 celsius) , and observed for a total of ten minutes with thirty second intervals which was when we recorded our observations. After observations, it was seen that normal conditions was the most preferred environment by the isopods. In the scenario the Isopods exhibited taxis behavior, which is behavior caused by factors such as light, temperature, water and such. Nothing physical, but rather environmental.
Ceratopsians and Pachycephalosaurs Around 144 million years ago, began the emergence of the Ornithischian dinosaurs during the Cretaceous period and diversified into North America and Asia. Ornithischians were classified as having a hip structure similar to that of birds, although they are not the descendants of birds. Marginocephalians, meaning "fringed heads" are a group of Ornithischians that have a distinctive skull structure, consisting of a slight shelf or bony frill on the back of the skull, a unique palate, and a short hip structure. These herbivores include two major groups: the Ceratopsians and the Pachcephalosaurians. These plant-eaters include the Ceratopsians, horned dinosaurs such as the Triceratops, Styrachosaurus, Pentaceratops, and the Protoceratops.
From a crab to a barnacle, crustaceans are a diverse group of animals that inhabit much of the world. This lesson will explore what it means to be a crustacean and will also provide some example organisms.
For this paper, we will be talking about relational communications and Goffman’s terms. The definition of relational communication is “communication processes in personal relationships such as romantic, family, and friendships. We assess the role of communication in developing, maintaining, and dissolving relationships, how communication impacts partners and their relationships, and how to improve relational quality or individual well-being through communication. Recent topics examined include conflict mediation, relational standards, relational uncertainty in dating relationships, and communication environments in families” (n.d.). As it has said, it is about the relationships in our life. Goffman also stated that there was a front and

An example would be the firefly squid, which has thousands of photophores, or organs that emit a deep blue
This research focuses on Gambierdiscus toxicus which is an armored, marine, benthic species in the phylum Dinoflagellata. It has an epitheca and a hypotheca, that is very similar in size, compressed anterio-posteriorly. The theca is covered with numerous deep and dense pores which are very thick. This species is autotrophic creating energy via several golden-brown chloroplasts (Hackett et al 2004), but is also heterotrophic and hence is referred to as mixotrophic. It has a ventrally – oriented crescent shaped nucleus. (Adachi & Fukuyo 1979). It usually inhabits warmer waters such as bay, mediterranian, tropical/sub – tropical in North/Central America (Shiumuzu et al 1982; Loeblich & Indelicato 1986), Asia/Pacific (Holmes & Tao 2002; Lu & Hodgkiss 2004) and has recently been identified in the Mediterranean (Aligizaki & Nikolaidis 2008). These authors identified the organisms to genus level, at best of their effort, so may have been one of the less common members of its genus although it is unlikely.
Killer whales communicate by a series of clicks and whistles called vocalization. Each pod, or family, has their own unique language. This gives whales the ability to identify their own pods. Orcas have a brain that is about five ti...
Breathing underwater explored many conflicts throughout the novel , such as spousal abuse , family abuse , the consequences of poor communication and low self esteem , but in my opinion the most important conflict in this novel was the consequence of poor communication. In a Dictionary communication means the imparting or exchanging of information or news. One of the many factors that communication has is honesty, honesty is one of Mario’s rules for his counseling class. Not having communication is not understanding your partner unless you can read minds you can't know what they’re feeling or thinking. Communication can help you understand why someone acted the way they did or
What they do is produce light (bioluminescence) that helps the squid camouflage itself at night. The squid has a special way of sensing how much moonlight is coming down, and then using a shutter, can control how much light comes out. This makes the squid not cast a shadow, making it harder for predators and prey to see it. During the day, the squid pumps out the dead bacteria, and the process starts again. What her team did was look at how these bacteria produced their light. When they were in a dilute solution with very few bacteria, then they did not produce light. But when there were many bacteria, they did produce light. The reason this happened is because the bacteria produce these chemical messengers called Quorums, which help the bacteria know how much of them there
Occasionally, a giant squid will wash up on shore or will come up in a fishing net, which has allowed scientists to get a close observation of these squid and their anatomy.
First of all, an octopus is a cellapod. Which means it has a soft body, and no bones. An octopus also has eight arms, large useful eyes, and suction cups. ( Octopuses and Squid, page 6 by: Tori Miller.) All of these traits are mostly used for hunting. Eight arms come in handy when your prey is fast and can get away easily, large eyes are useful when you need to see in the dark or the depths of the ocean, and suction cups are used when they need to grab hold of something.( Octopuses Squid, page 14.) ( National Geographic, Octopus Facts.) Octopuses have blue blood caused by copper and bag like bodies. When born they're 1/4 of an inch and don't rely on...
"Koko is the kind of daughter who, even at 32 likes to settle into her mom's lap and cuddle. Never mind that she is 300 pounds" (Adams 1999). When Koko, a baby gorilla at the San Francisco Zoo, was adopted by her mother, Dr. Francine "Penny" Patterson, she was suffering from malnutrition. Koko, one of the most recognized gorillas in the world, is able to communicate with humans through American Sign Language or Ameslan, the hand of the deaf, used by an estimated 200,000 deaf Americans (Patterson 1978). Koko is famous for her ability to communicate with humans and her active role in saving her endangered species.
Ants cant use their jaws to talk, but they do communicate, and very well. One way they communicate is by touching each other with their antennae. They also communicate by producing chemicals called pheromones. These chemicals can give different kinds of information. The taste or smell of a certain pheromone can warn of danger, or mark a trail.
